Abstract
Yttrium iron garnet (YIG) thin films substituted erbium ions (Er+3) Er0.4Y2.6Fe5O12 films were prepared by a sol-gel method at different temperatures which varied from 800 to 1000°C for 2 hours in air. Magnetic and microstructural properties of the films were characterized with X-ray diffraction (XRD), the field emission scanning electron microscopy (FESEM), and vibrating sample magnetometer (VSM). The XRD patterns of the sample have only peaks of the garnet structure. The lattice constants decrease, while the particle size increases from 51 to 85 nm as the annealing temperature increases with average in thickness of 300 nm. The saturation magnetization and the coercivity of the samples increased from 26 (emu/cc) and 28 Oe for the film annealed at 800°C to 76 (emu/cc) and 45 Oe for film annealed at 1000°C, respectively.
Highlights
The study of yttrium iron garnet (YIG) thin films is becoming more important because of properties that can be extensively used in optical communication [1], magneto-optical devices, and applied in microwave [2]
This paper focuses on the influence of low concentration of Er+3 ions substituted YIG thin films (Er0.4Y2.6Fe5O12) at different annealing temperatures
We have studied the synthesis of YIG substituted (Er+3)
Summary
The study of yttrium iron garnet (YIG) thin films is becoming more important because of properties that can be extensively used in optical communication [1], magneto-optical devices, and applied in microwave [2]. YIG is the most representative and well-known compound among the rareearth garnets and various magnetizations can be achieved by substitution process. Thin and thick films have been produced in garnets using different methods such as liquid phase epitaxy, sputtering, chemical vapor deposition, liquid phase epitaxy, laser ablation, and sol-gel. In a YIG system, nonmagnetic Y3+ ions occupy dodecahedral {c} sites and magnetic Fe3+ ions occupy octahedral [a] and tetrahedral (d) sites. The magnetic moment of Er3+ substituted for Y3+ in {c} sites, Journal of Nanoscience which can be parallel to the magnetic moment of Fe3+ in the d-sites, meaning that the saturation magnetization of Er:YIG is different from that of pure YIG. This paper focuses on the influence of low concentration of Er+3 ions substituted YIG thin films (Er0.4Y2.6Fe5O12) at different annealing temperatures
